GT12M Bronze Thru-Hull Transducer - 350W - 0°

Engineered for reduced drag and premium sonar performance on midsize fishing and cruising vessels, this flush-mounted, 350-watt mid-band CHIRP transducer accurately depicts fish arches, underwater structures, and bottom depth readings on your display.

Midband Chirp Traditional Sonar

This 8-pin, 350-watt bronze thru-hull transducer utilizes high-definition mid-band CHIRP sonar, effectively identifying fish and structures down to 800 feet in saltwater and 1,200 feet in freshwater.

Broad Frequency Range

Optimize your fishing experience with the suitable frequency for your specific waters. The transducer operates within a medium frequency range, pulsing from 85–165 kHz, presenting a wide coverage area, detailed fish arches, and precise depth readings.

Optimum Ping Sensitivity

With exceptional sonar sensitivity, low noise levels, high resolution, and improved target separation, this durable transducer significantly enhances your ability to identify fish and structures on compatible chartplotter displays.

Thru-Hull Installation

The robust bronze housing and stem facilitate straightforward thru-hull flush mounting, ensuring minimal drag and optimal beam orientation for clear sonar returns.

Auto-ID Technology

Experience hassle-free plug-and-play operation with Garmin’s auto-identification technology, which autonomously configures the sonar according to the utilized transducer.

Fits Various Hull Types

Adaptable for a range of boat hull materials, including fiberglass, composite, and wood, the transducer is available in different tilt variations to support deadrise angles from 0° to 20° without requiring a fairing block.
